improvement the following is a specification.

Ifhis invention relates to' means for sup ply ng fluid pressure intermittently or penodically for any suitablefpurpose where is desired to utilize the fluid'under pressure in'a series of blasts of greaterbr'lessf'fre quencyand duration, and has foritsobject to provide an i'mproved cam device for con-- trolling the successive admissions of fluid pressure, or for other purposes."- f v While .my improvementis adaptedlfor a variety of uses, it is particularlyfdesigiied to be employed in connection with a 'm'e chanical stoke'r' for forcing the fuel into the firebox, as shownand describedirimy prior pending applicationSer. No. 565,579,

filed June 7, 1910. In this prior'otistruo tion, the admissionof fluid "under; pressure to the fuel distributer noztles is controlled by a valve operated by a pivoted lever one end of which carries 'a' reuetteafin 'msan the periphery of a cam disk upon whichtlie cam members are pivoted and adapted to be turned to different positions to extend the different cam surfaces beyond the periphery of. the disk to engage the roller and actuate the valve.

According to one of the features of my present improvement, the cam members are slidably mounted to be reciprocated on the disk and are provided with a positive spring actuated latch mechanism which prevents any accidental or undesired displacement of" the cam members, and-also renders the adjustment of the same positive and certain.

In the accompanying drawings: Figure 1 is a front elevation of my improved controller camdevice, the valve being shown in section; Fig. 2, a face view of the body portion of the cam disk with the cover and cam members removed; Fig. 3, a vertical transverse section of the same; Fig. 4, a transverseiisection taken on the diagonal line 00 m offFig. 2; Fig. 5, a rear elevation of the "camdisk; and, Fig. 6, a vertical transverse section ofthesairie showing one of the cam members extended; f

As set. forth in my prior application," the valve for controlling the supply or flow of the fluid under pressure comprises a casing, 32,'containing a valve proper, 31, with stem, 34, anda spring, 33,- normally holding the valve closed on its seat, the casing having a bracket arni', 37, to which ispivoted the lever, 36, adapted to operate the valve stem and at the other end carrying a roller which bears against thecam disk.

- According to present construction, the cam disk is preferably formed in two parts, the body portion, 35, and cover, 35. A plurality of- 'caiii members, 39, are slidably mounted on the cam 7 disk, and are adapted to be reciprocatedby means of haiidles, 42, sothat the cani" surfac'es, '40, at the outer ections, 51, adapted to engage notches, 52,

when in the retracted position, and be held therein by the spring plungers, 49, located in the recesses, 48, and bearing against the under side of the cam members. When the cam members, are adjusted to the extended position, the projections, 51, engage the ends of the notches or slots, 50. The latch projections engaging in the slotsor notches pos- .1tively prevent any accidental or undesired displacement of the cam members by pressure applied to the cam surfaces but the cams may be readily adjusted from one position to the other by the handles which'may be pushed inward sufliciently to compress -'the;.'spring and clear the slots or notches whenever it is desired to adjust the cams. Any desired number of cam members may be employed and the width and contour of the. respective cam surfaces may be varied tion, the valve will be intermittently opened and closed and the frequency and duration of such admissions or blasts may be varied as desired to suit any conditions.
